The only book you need if you're going back in time

Bestselling author and time-travel enthusiast Ryan North shows you how to invent all the modern conveniences we take for granted--from first principles. This illustrated manual contains all the science, engineering, art, philosophy, facts, and figures required for even the most clueless time traveler to build a civilization from the ground up. Deeply researched, irreverent, and significantly more fun than being eaten by a saber-toothed tiger, How to Invent Everything will make you smarter, more competent, and completely prepared to become the most important and influential person ever. You're about to make history. . . better.

Reading it brought me back to all the afternoons I’d spent as a kid flipping through the big reference books in my local library, and then eagerly running home to tell anyone who’d listen what I’d learned. One of this book’s great achievements is the way it so gracefully combines scholarly rigor with youthful wonder.” —Electric Literature
